Semantics: A New Way to Organize Data
Data is stored in Triples, expressed as: Subject
: Predicate : Object
John Smith : livesIn
: London
London
: England
: isIn
Query with SPARQL, gives us simple lookup .. and more
Find people who live in (a place that's in) England
"John Smith"
"London"
"England"
